In order to realize real-time control, the paper studied two kinds of closed-loop control structures such as based on scalar quantity and double closed-loop control structure, moreover established their control structure, then simulation to the double closed-loop control structure of voltage source type matrix converter. The simulation results indicate that reach the real-time control requests, the system dynamic response performance is good, the converter input output can be adjusted in the short time.

为实现电压源型阵变换器的实时控制要求，论文对基于标量控制和双闭环的两种电压源型矩阵变换器闭环控制结构进行了研究，分别建立了这两种闭环控制的控制结构，并且对电压源型矩阵变换器的双闭环控制结构进行仿真，仿真结果表明达到了实时控制的要求，系统的动态响应性能好，变换器的输入输出能在较短的时间内达到调节。

In the traditional experimentation of farming , we must do scarification,shoveling, pressing the time between every two working procedure is long,the efficiency is low,and it will also expand a large number of the labour order to work out this problem ,we should create a new kind of can take the place of -speed digital multifunctional soil bin carriage is one equipment which can acord with these can do scarfication,shoveling,pressing at the same time ,and it can control each working procedure shortens the time between every two working procedure,and improve the efficiency.

传统的耕作试验需要单独进行松土、铲平、压实、旋耕等工序，各工序的间隔时间较长，效率较低，而且要消耗大量的劳动力，为了解决这一问题，我们迫切的需要研制出一种新型的机械设备，用它来代替人力。高速数字多功能土槽试验台车正是要符合这些要求的一种机械设备，它能够将松土、铲平、压实、旋耕等各道工序连为一体，并且能够单独控制各道工序。

In the process ofnavigation of INS/Scene Matching the aerocraft will save the land information of undersurface offly orbit in the memorizer which has been scouted in advance. While the aerocraft fly thescheduled position the sensor schlep will take the real time image like as RAR image. After thenthe real time image will match the reference image which has been stored beforehand and hasgeographic relation with real time image. Thus the position or horizontal and longitudinal distanceerror of the aerocraft can been fixed on. After that the navigation and control and guidance iscomplete.

在INS／景象匹配组合导航系统的导航过程中，飞行器首先将预定飞行轨道下面事先侦察到的一系列地面图像信息存到飞行器的存储器中，然后，当携带相应传感器的飞行器飞行到预定的位置时，便获取实时图，然后将实时图和预存的已知地理信息关系的基准图进行匹配比较，这样就可以确定出飞行器的当前位置或者偏离预定位置的纵向和横向偏差，从而完成导航和制导功能。

Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

然后用二能级模型解释了单、双、三光子激发原理，在理论上推导出了单、双、三光子吸收诱导荧光强度与脉冲强度以及脉冲作用时间的关系，并进一步研究了入射光时间分布分别为矩形、高斯型、双曲正割型时激发溶解在氯仿溶液中的C22H22N4O样品所产生的荧光峰值光强，结果表明激发光的时间分布对双、三光子荧光峰值强度的影响比对单光子的影响要大。
